Option B
Option B
Ok i just installed option b on my car and I was wondering is there a way too look and tell that its working for sure? Iv got the zzp kit but I routed it a lil different since my dual pass core are not swapped the way zzp has it on the diagram. My out cores are the two middle so it goes opt b and dual pass out connect to a T fitting that runs into the stock HE and that runs out to the ic pump inlet and then that runs to the top and bottom nipple of the dual pass that are inlets. Is this setup fine? iv noticed bubbles coming out of the big hose on the Opt B some im guessing that means it works.
I think you are supposed to have it set up pump>heat exchanger>manifold>pump. I was told the theory is if you have set it up pump>manifold>heat exchanger, the pump heats up the coolant after the h/e cools it and then it goes to the manifold. I don't know how much it will actually effect temps but it will work routed either way.

I know you don't want to hear it, but to do it right, pull the manifold, flip all the cores and re-route your hoses properly. Intercooler performance on these cars is so critical, you really are defeating the purpose of the upgrades if you aren't going to do them in a very specific way.
Pump doesn't create any meaningful heat, it doesn't matter.
You actually don't want to use the middle as the outlet, if you are coming straight up from the pump to the inlet. Reason being, you create a spot that can trap bubbles. If air is in the line and flows to the top core, it doesn't want to flow down to the middle cores and back out.

Hmm i dont really have the time or exp to pull all that stuff off, is they a way tho i can tell if the systen is bleeding tho? As i said i seen bubbles coming out of the big hose of the option b im assuing that means its bleeding.
I can prolly reroute my hoses to opt b big hose and dual pass middle nipple outlet to T that will flow into ic pump and the pump will flow in to the Heat exhanger inlet and then that will flow out to the top and bottom dual pass nipple inlets. Will this work better?
Ok ok i understand that i need to redo it and when i have few days off and can get ahold of my friends tools ill do it but inthe mean time can someone pls answer the other question. Iv got bubbles coming out of the big hose on opt b, is that working as intended? Aka is that mean its bleeding the air correct?
NO the bleed orifice is in the line going from the h/e to the top nipple in the tank. Look at the top of this picture you will also see the regular bleed line for the engine cooling system that runs from the top of the head over the rad hose by the coolant temp sensor (high point in the system) to the reservoir.
same deal. two independent cooling systems.

what I dont know is what a normal option b thats working looks like this is a video of whats happening just tell me if something is wrong with these bubbles or if its normal. I just need to know for right now is these bubbles a problem or if thats normal its gonna be a week or two before I can reroute this all and so I just need to make sure nothing is wrong with it till then.

If you are getting bubbles coming out of the bottom hose instead of the smaller hose, it is completely routed wrong. You need to redo everything unfortunately. I have fixed two peoples routing so far. Essentially you are putting air into the system instead of taking it out.
Well I talked to james and staged07ss and both of them said that the bubbles coming out of the hose was the system burping itself so Im just let it burp and see what happens.
^^^ thats simply not the way a cooling system works, but it doesnt matter at the end of the day, you will do whatever you chose to do. Your dual pass is not put together right, and thats the end of the story as far as anyone here trying to help you is concerned; my opinion.

I do thank you for pointing out I need to reroute my hoses and the cores but u never did answer the question about the bubbles, u just kept ignoring it even tho iv said already I know that I need to change that but I cant right now, it seems bubbles is a normal thing to happen with the option b during the install and thats all I wanted to know not keep having someone repeat the same thing over and over that I already know I need to fix.
The bubbles are not air being bled out. The bubbles are being created on an ongoing basis, stopping the system from working properly.
also it is NOT normal to have bubbles coming out of the main feed hose to the reservoir. The bleed line with a restrictor eliminates air from the system from the highest part of the h/e cooling system which is the top of the Heat exchanger.
Vander. Bottom line is ur install is incorrect. So asking question if bubbles in a certain hose is ok doesn't make sense. It's installed wrong and not functioning right. Only air u should see is in the Lil hose from stock h/e to the overflow tank. And it should stop seeing them pretty fast if all is hooked up well. Good luck buddy.
It takes a man to admit when he is wrong, and while i was going off of info from someone else i was told this will work and it wouldnt work no matter what i did, i was seeing iats2 of 140 to 160 just cruise or idle and well yeah i didnt do any pulls, i put back in the stock filler neck and just bleed the system woth dual pass only and my iat2s are back around 120-130ish idle and 100 -110 cruise, my dual pass is still set up the same so im guess the dual by itsself can work being backwards but not with the opt b. anyways im sorry powell, i got ill cause i was not getting an answer to my bubbles question till later on so i got mouthy with u, i do thank everyone for there advice.
Well updated i sold the opt b to a friend that lives near me and i installed it for him, his cores where setup the correct way so i was able to install it with no problem, figured id post this since i had a troll saying i cant figure out how to run an opt b.
